To provide an ultrasonic diagnostic apparatus capable of detecting a bone surface and a joint cavity region with high precision without performing pattern matching in an ultrasonic image of a joint site. The ultrasonic diagnostic apparatus is characterized in that it includes: a component specifying unit that sets a depth direction of the subject approximately perpendicular to the surface of the subject in the ultrasonic image as a first direction, and a direction perpendicular to the first direction as When it is the second direction, the first determined pixel whose pixel position in the second direction is N (N is an integer greater than or equal to 1) and the pixel position in the second direction is The second determined pixels of N+1 are associated in such a way that the brightness of the second determined pixel is large and the first determined pixel and the second determined pixel are close to each other, thereby detecting more than one characteristic line from the ultrasonic image, based on the characteristic line at the second Which of the feature lines represents the boundary between the constituent elements is specified in order in one direction, and an image portion representing the boundary of each constituent element is specified.
Description
[0001] Japanese Patent Application No. 2013-169527 filed on August 19, 2013, Japanese Patent Application No. 2013-171033 filed on August 21, 2013, and Japanese Patent Application No. 2014-160638 filed on August 6, 2014 The disclosure contents of the claims, the specification, the drawings, and the abstract included in the document are incorporated herein by reference in their entirety. technical field [0002] The present invention relates to an ultrasonic diagnostic apparatus, an ultrasonic image analysis method, and a program for performing ultrasonic diagnosis by bringing an ultrasonic probe for transmitting and receiving ultrasonic waves into contact with the body surface of a subject, especially limb joints. Background technique [0003] In recent years, it has become more and more common to use ultrasonic diagnostic apparatuses for the evaluation of disease activity of arthritis including joint rheumatism. In the evaluation of disease activity, B-mode images and power ...
